This shit started long ago. 1991, an innocent man went to prison in Germany.

How? A bank robbery, very grainy footage, you can just see that the robber is fat and masked. So they arrested some other fat guy and got an expensive "biometric expert" who "identified" him as the robber. How? The ear. Certainty? 100 %.

When they got the real guy, you could see that the ear is not similar whatsoever. Neither is anything else, except for the body type.

Since that was not in the US, he got 30k compensation, but had to "pay back" 10 per day for the food he got over 9 years. In a civil case 6 years later he got 150k compensation from the "expert" (which usually does not happen, but he fucked up so hard and got more innocent people convicted after that).
